Bio-Implantable Microsystems such as the cardiac pacemaker, retinal and neural implant provides substitute for a missing biological part, support an impaired biological structure or even upgrade the existing biological system. These microsystems require ultra-low power miniature integrated circuit technology for long term reliable operation. For energy constraint applications like the implantab...

This paper presents an implantable wireless battery recharging system design for bladder pressure chronic monitoring. The wireless recharging system consists of an external 15 cm-diameter 6-turn powering coil and a silicone-encapsulated implantable rectangular coil with a dimension of 7 mm × 17 mm × 2.5 mm and 18 turns, which further encloses a 3 mm-diameter and 12 mm-long rechargeable battery,...
